Ok this is me. I consider Catholicism, Mormonism, Jehovah Witness, Hinduism, Unitarian church, Buddhists, Calvinism, Islam, Judaism, Zionism, and many others to be false. None of those are a race. I don't consider any country to be a race. Just because there may be more Christians in the US doesn't mean we are a race.
Racism to me is judging a person by their skin color and not their actions. And yes I am aware there are many Catholics on this site.
